Is 3CX really free?+
Yes — 3CX StartUP FREE supports up to 10 users at no cost. Paid tiers unlock more users, multi-site, call centre features and contact-centre integrations.

Absolutely. NOX ports your existing Australian numbers from Telstra, Optus, TPG and others, or provisions new local, 1300 or 1800 numbers.

Yes. 3CX integrates with Microsoft 365, supports SSO, and can route calls between Teams and 3CX users.

Not necessarily. 3CX supports Yealink, Snom, Fanvil and most existing SIP phones. Many customers run softphone-only on desktop and mobile.
Where is the system hosted?+
